If you prefer a more natural solution, then look for acidophilus tablets that help to kill off the yeast. Natural yogurt also contains live acidophilus bacteria. Some women may choose to apply yogurt containing these bacteria directly to their vagina to clear up their yeast infection. Also, you may want to take steps to help prevent a yeast infection from occurring in the first place. Make a paste from garlic cloves and apply it over the area of the vagina. This will cause some burning but it will give relief from the yeast infection by reducing the growth of candida fungus.
